More than 14 years of experience in .NET software development and the Microsoft Tech Stack. - .NET Framework/.NET Core experience - Expert knowledge and huge background in web development: .NET Core, Blazor, .NET MVC, WebAPI, AngularJS, CSS/Bootstrap. Service oriented architecture, cloud development in Microsoft Azure, Azure Service Bus, Event Grid - Desktop development of WPF, WinForms applications. Windows services, workers, UDP/TCP game servers. - Automation, bots and scraping with Selenium Web Driver - Game development in Unity 3D for desktop and mobile platforms, integrations with Google Play Services, Steam SDK.

I build custom web scraping systems in Python for JavaScript-heavy sites, browser automation flows, login-protected pages, and recurring data collection pipelines. If you need clean structured data delivered from a website into CSV, Excel, Google Sheets, APIs, or a database, I can build the scraper and the surrounding workflow. What I can help with: - Web scraping and data extraction - Python scrapers for dynamic websites - Selenium and browser automation - Reverse engineering XHR / network requests - Anti-bot aware scraping workflows - Scheduled scraping pipelines - Data cleanup, normalization, and delivery I work on both one-off scraping jobs and long-running scraping systems. My focus is reliability, maintainability, and clean output rather than fragile scripts that break after a small site change. Common use cases: - Lead and business directory scraping - E-commerce product and pricing scraping - Real estate and listing scraping - Report download automation - Internal dashboard and dataset generation Tech I use when appropriate: Python, Selenium, Playwright, requests, aiohttp, BeautifulSoup, lxml, browser automation, APIs, Docker If you have a target site and sample output format, send it over and I can tell you the best scraping approach.

Senior QA Engineer (API * Automation * Performance) | Remote Contract & Part-Time I am a Senior QA Engineer with 5+ years of hands-on experience testing complex software systems across multiple domains — including telecommunications, compliance platforms, e-commerce, and data-driven applications. I specialize in API testing, automated testing (Selenium, WebdriverIO/TypeScript, Python), performance testing (load & stress), backend validation, and quality process improvement. I help teams deliver stable, reliable releases by designing effective test suites, automating regression tests, and validating backend logic and APIs. I’ve worked both in full-time roles and contract environments, and I’m now focused on remote, part-time or long-term contract engagements (10–20 hrs/week). Clients hire me for clear communication, strong problem-solving skills, reliable delivery, and a proactive approach to quality and testing challenges. Let’s discuss how I can help ensure your product meets the highest standards of quality.

I’m a QA Engineer with 3+ years of experience in manual testing, recently expanding into test automation with modern frameworks and tools. Over the past few months, I’ve been actively working on a real project where I design and maintain automated tests using Cucumber, WebdriverIO, and TypeScript. This hands-on experience allows me to build scalable test scenarios, improve regression coverage, and contribute to faster and more reliable releases. In addition to that, I have practical experience with Playwright and Selenium (including Selenium IDE), as well as Appium for Android testing, giving me flexibility across web and mobile automation. My core strengths include: Test automation with Cucumber + WebdriverIO + TypeScript UI and end-to-end testing (Playwright, Selenium) Mobile testing (Appium – Android) Functional, regression, and integration testing API testing with Postman and backend validation with SQL Test case design, execution, and bug tracking (Jira, Xray, Confluence) I’ve worked on complex systems such as telecom billing and CRM platforms (Vodafone Italy), where precision and deep system understanding are critical. I’ve also tested HR software platforms, focusing on usability, data integrity, and consistent user experience. I’m comfortable working in Agile teams, collaborating with developers, and quickly adapting to new domains and technologies. Additionally, I leverage AI tools like ChatGPT and Claude to generate smarter test scenarios and improve test coverage. 🔹 Tools & Tech: WebdriverIO, Cucumber, TypeScript, Playwright, Selenium, Appium, Postman, SQL, Jira, Git 🔹 Basic knowledge: CI/CD (Jenkins), Docker, JavaScript 🔹 Languages: English (fluent), Bulgarian (native) I’m focused on delivering reliable, well-tested software and continuously improving my automation skills. If you’re looking for a QA who can contribute both manually and with automation — I’m ready to help.
